BART SGANLAN, or OMAHA, NEBRAsxn Romany- R SH V Application filed. April2, This invention relates to rotary brushes and an object of theinvention is to provide for rotating a brush in a fixed handle forthepurpose of cleaning strainers, graters, salt and pepper shakers, combs,filters or any foraminous material. 7

Further objects of the invention are to pro vide a devioeof thecharacter referred to V which is-strong, durable, thoroughly reliablefor its intended purpose, very simple inits method ofassembly, andcomparativelyin' expensive to manufacture andoperate.

With the foregoing and other objects in view, the invention consists ofa novel construction, combination and arrangement of parts, as will behereinafter more specifically described and illustrated'in theaccompanying parts, wherein isv disclosed an embodiment of theinvention, but it is to be on derstood that changes, variations and modiindicates an elongatedsolid handle formed] of any: desiredmaterialQl/Vhile the configuration of the handle is shown-to be frusto-'conical, the shape thereof maybe changed as desired without departingfrom the spirit of the invention Extending inwardly from one end of thehandle is a socket 6 which extends along the longitudinal median for aportion of the length of the. handle and ter-n minates at its inner, endina transverse sec tional opening 7 vextending entirely throughthe'handle 5. v i a Y 7 Rotatably mounted-in the socket 6 is tubularsleeve '18 having the interiorwalls at one end'thereof provided-with aperipheral thread 9 for threadably supporting the shank 10 of a screw.The screw ha's an m drawings wherein like reference 1929. Serial No.351,932., 1 to larged headll projecting outwardly from the inner end ofthe sleeveof'larger diameter than the socket 6 which headprojects intothe transverse opening 7 to prevent axial movement of the sleeve 18. Ashaft indicated generally at 12 has the inner end 13' anchored in theother end of the tubular sleeve 18 by, means of solder l4; orother'suitable material. I v

The shaft 12 is preferably formed of metal of suchstrength as to givethe desired rigid-. ity to the brush; The shaft 12 is formed of a pairof strands .15, 16 spirally wound about eachother and having bristlesanchored be- 7 tween the windings from the shaft 12. e

The, bristles '17 may and projecting radially be of such quality aswill-be'necessary and the configuration of the, v

outer surface of the bristles 17 is preferably of cylindrical shape. 7 Y

In the assembly o'f'the brush in accordance with this invention, theshaft 12 and the bristles may be formed in one operation, the sleeve 18and the handlej5 formed in another operation whereupon the shaft may besoldered within oneend of the sleeve 18 and very simply andeasilyassembled in the handle 5. Y t

Having thus described my invention, what I claim as new is: I

In a device of the character described, a handlahaving a bearing socketextending from one end of thehandle inwardly, said handle formed with atransversely extending opening at the inner end of the socket andcommunicating with said'socket, a tubular sl'eeverotatably mounted inthe socket,

means on "the inner end of'thesleeve flaring outwardly to the transverseopening to prevent axial movement thereof, a-shaft anchored in the outerend of said sleeve andprojecting forwardly: thereof and'bristlesanchored in the shaft to provide an abrade 7 ing surface, saidmeansconsisting of afscrew, I

threadedly 'engagingthe.v inner end of thefl i "sleeve andithe'headthereof confinedin the transverse opening. o
